BOBBIN-SMASI-I PREVENTER.

Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed April '7, 1913. Serial No. 759,338.

To all whom it may concern Be it known that I, J UNIUS H. BAGWELL, a'citizen of the United States, residing at Greenville, county of Greenville, State of South Carolina, have invented an Improvement in Bobbinmash Preyenters, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter described relates to looms, and more particularly to looms of the filling replenishing type, wherein upon failure of filling from any cause a filling carrier with a fresh supply of filling is transferred to the shuttle.

As well known by those skilled in the art, it sometimes happens that the filling carrier or bobbin placed in the shuttle by the transferring mechanism fails to be properly positioned in the shuttle. This may happen from various causes well known to those familiar with this class of machines. For instance, the spring holding jaws in the shuttle may fail to properly catch the rings on thebase of the filling carrier or bobbin; the bobbin or carrier itself may have a defective end; or the rings on the base of the bobbin or carrier may not be inproper position or they may be otherwise defective. In such cases the tip end of the carrier or bob bin will or may project above the top of the shuttle and the shuttle be picked to the opposite end of the lay. No harm mayibedone on this pick, because on this pick following replenishment, the filling carrier passes through the shed base end first, but on the next pick the tip of the filling carrier goes first, and being above the top of the shuttle, it will catch in the warp threads with the result that a smash occurs, the length or width of which may cause serious loss and waste of time. When a filling carrier or bobbin has been thus improperly positioned in the shuttle, a slight touch or knock on the tip end of the filling carrier or bobbin in a downward direction will often be sufficient to cause the carrier or bobbin to properly seat itself between the. spring holding jaws of the shuttle, but should this not occur itcis desirable that the filling carrier or bobbin,

be thrown out of theshuttle before the hereinbefore-nientioned smash becomes possible. With these general facts in mind the aims and purposes of the present invention will best be made clear from the following de scription and accompanying drawings of one form of means for carrying the invention into practical effect, it being under stood, of course, that the details thereof may be varied within the true scope of the invention as defined by the claims.

In the drawings :Figure 1 is atop or plan viewof sufiicient portions of the lay, shuttle boxes, and filling replenishing mechanism to make clear the association of the present invention therewith, it beingnoted that the central portion of the lay is broken away to permit both ends thereof to be illustrated; Fig. 53 shows the shuttle at the filling replenishing side of the loom being picked after the action of filling replenishment and the tip of the filling carrier above the top of the shuttle; Fig. 3 shows the shuttle at the opposite side ofthe loom and being picked toward the filling replenishing side; Fig. 4 is a cross-section on line 4:--4, Fig. "l; and Fig. 5 is a cross-section on line 5-5, Fig. 4. p

The loom frame for supporting the loom parts and the filling replenishing mechanism may be of any usual or desired form or character.' In the present illustration, the filling replenishing mechanism is de signed to transfer a filling carrier 3 from a source of supplyto the shuttle a when the i lay is approximately in front position, and may comprise a bracket portion 2 secured to the loom frame, a transferrer 5 mounted upon a rod 6 and normally held in raised position by a spring 7, said 'transferrer 5 being made operative to transfer a filling carrier from the source of supply. to the shuttle upon failure of filling from any cause or upon substantial. exhaustion thereof. Since the structural character of filling replenishing mechanisms and their operative characteristic are well understood by those skilled in the art, and since the present invention is not dependent upon any particu lar form or structure of such mechanism, it has not been deemed necessary to illustrate and describe in full any such mechanism beyond that illustrated in the drawing as typifying any usual form.

The lay 8, which may be of usual construction, is provided with shuttle-box 9 at each end, each of said shuttle boxes having a front wall 10, a rear wall 11, a top plate 12, and a binder 13. One wall preferably the bottom, of the shuttle-box 9 at the filling replenishing side of the loom is slotted, as usual, for the passage of a filling carrier as it is discharged from the shuttle. These parts, as well as the picker stick ll, the picker 15, the binder fingers 16 and associated elements may be of usual or any desired form or character, the general construction of the parts thus far described being such that upon indication of filling failure from any cause, as usual, the filling replenishing mechanism will be set in action as the lay beats up and transfer a filling carrier 3 from the source of supply to the shuttle ,4, the filling carrier previously in the shuttle being discharged through the slot or opening provided for this purpose in the wall of the shuttle-box.

It will be noted by reference to Fig. 1, that when the shuttle is in the box adjacent the filling replenishing mechanism, that the tip end of the filling carrier is directed toward the end of the lay at that side and that this is the position of the filling carrier when transferred from the source of supply to the shuttle. As hereinbefore noted, it

sometimes happens that the filling carrier may not be properly positioned in the shuttle when transferred thereto. The tip end thereof may project above the top surface of the shuttle 4:, as indicated in Fig. 2. If this condition is maintained when the shuttle is passing tip end first through the shed, the tip of the filling carrier is liable to engage the warp threads and cause a smash. The present invention seeks to prevent this defective action, and to this end provides means whereby should the tip end of the filling carrier be above the top surface of the shuttle following filling replenishment, such' tip end of the carrier will be given a tap or touch before the shuttle enters the shed on the first pick after replenishment, This in many cases is calculated to cause the carrier to become properly seated in the shuttle, whereupon weaving may proceed without interruption. On the other hand, it may sometimes happen that this tap or touch upon the tip of the filling carrier may not serve to properly place the carrier in the shuttle, and the present invention contemplates that under these conditions the filling carrier or bobbin be thrown from the shuttle box before it enters the shed on its way to- Ward the filling replenishing side of the loom.

As a good convenient form of means to the above ends, there is mounted upon the top plate 12 of the shuttle-box at the filling replenishing side of the loom, a yielding element which extends over the top of the shuttle-box, the construction being such that should the filling carrier in the shuttle have its end or tip portion extending above the top surface of the shuttle, as indicated in Fig. 2, said tip end portion will contact with the yielding element as the shuttle moves from the filling replenishing side of the loom and be given a tap as the shuttle passes under said element. In many cases this will be suflicient to cause the carrier to become properly seated in the shuttle.

In the form of the invention shown, this yielding element comprises a part 17, which for identification, will be hereinafter referred to as a deflector or filling carrier deflector, such term, however, being one of identification only and not of limitation.

The part 17 or deflector is extended over the top of the shuttle-box, as in Figs. 1 and 2, andmay be secured to the top plate 12 thereof. As a convenient means to this end the deflector 17 is hinged at 18, Figs. 1 and l to a strap or plate 19 which is secured to the top plate 12 of the shuttlebox by appropriate means, such for instance, as the screws 20. Obviously the deflector might be secured in position over the top of the shuttle-box by other means, but that shown and described is a good form of one of such means.

The deflector 17 is secured in position over thejtop of the shuttle-boxat the inner portion of said box as indicated in Fig. 1, so that the filling replenishing mechanism may properly transfer a carrier to the shuttle without interference from the said defiector. 7

It will be noted by reference to Figs.-2, 4i and 5, that'the deflector is provided with a lower inclined surface 21. This inclined surface may conveniently be formed of a metal piece which may be appropriately hinged to the strap 19 at 18 as hereinbefore described. The inclined surface 21 at the filling replenishing side of the loom extends upwardly andtoward the end of the lay, (see Fig. 2). Should a filling carrier be transferred vto the shuttle and have its tip extend above the top of the shuttle, as indicated in Fig. 2, and then be picked from that shuttle-box in the direction of the arrow, Fig. 2, it will be apparent that the tip of the shuttle will contact with the inclined surface of the deflector 17 as the shuttle moves under the deflector. In order that this action may be yielding in character, the deflector 17 is normally underthe action of a spring 22 which serves to hold the deflector in its normal operative position extending over the top of the shuttle-box. Should the tip of the carrier fail to yield as the shuttle passes beneath the deflector, the deflector itself will yield upwardly and permit the shuttle and misplaced carrier to pass in the directioiiof the arrow, Fig. 2, to the opposite side of the lay,

Should the tip of the carrier or bobbin still remain projecting beyond the top of the shuttle when the shuttle reaches the box're mote from the filling replenishing side of the loom, it is desirable that the carrier or bobbin be thrown from the shuttle before it enters the shed. To this end there is mounted at the inner end portion of theshuttlebox at that sidecf the loom remote from the filling replenishing mechanism, another deflector 17, which upon movement of the shuttle in the direction of the arrow, Fig. 3, will engage the tip portion of the bobbin and lift the bobbin bodily from the shuttle by turning it upward, as will be clearly understood. To facilitate this action, the deflector 17 has the inclined surface 23, which may be formed of any suitable material calculated to prevent injury to the yarn on the carrier. In the present form of the invention, the deflector has a piece formed of wood secured to the metal strap portion 21 by suitable screws, as indicated in Fig. 4.

It will be noted that the deflector 17 on the side of the loom remote from the filling replenishing mechanism has its inclined surface 23 extending upward and toward the middle of the lay, whereas the deflector on the opposite side of the loom is reversely situated. The effect of this arrangement is that the deflector on the filling replenishing side of the loom acts by its inclined surface 21 and the yielding character of the deflector, to give to the tip of the bobbin a yielding touch or tap as the shuttle passes beneath the deflector, and this same action may take place as the shuttle passes into the box at the opposite side of the lay; but on the return of the shuttle toward the filling replenishing side of the lay, the inclined surface 23 will engage the tip end of the bobbin as indicated by Fig. 3 and cause the ejection of the bobbin or filling carrier from the shuttle before it enters the shed.

In some cases it may be desirable to have only one deflector, that at the filling replenishing side of the lay, but usually one of such deflectors would be placed over the top of each shuttle-box, substantially as indicated in Fig. 1.

Should the filling carrier or bobbin be thrown from the suttle in the manner hereinbefore described, it will be deflected toward the front of the lay by the surface 24: of the deflector where the inclined surface 23 merges into the inner part of the deflector adjacent its hinged mounting, though this feature may not always be essential.

While the form of deflector described constitutes a convenient and practical embodiment of the present invention, it is to be un-,

derstood that the invention is not circumscribed by the details thereof, but is defined by the claims in its true scope.

What is claimed is I I y 1. In asmash preventer for looms, the combination of a lay and shuttle-box, means extending over the shuttle-box to contact with and give a positioning impulse to a filling carrier improperlypositioned in the shuttle as the shuttle moves out of the'shuttie-box and means extending over the shuttle-box at the opposite side of the loom to prevent the filling carrier from again passing through the shed in case the first-named means has failed to properly position it in the shuttle. V j j 2. In a smash preventer for looms, the combination of the lay and shuttle-boxes, filling replenishing mechanism, means to give a positioning impulse to a filling carrier improperly positioned in the shuttle when the shuttle moves toward the other shuttle'-box, and means to eject the filling carrier from the shuttle upon failure of said first-named means to properly position the filling carrier in the shuttle as the latter passes out of the shuttle box.

4. In a loom, the combination of a lay, a shuttle-box at each end of the lay, means to engage a filling carrier improperly positioned in a shuttle and impart a positioning impulse thereto as the shuttle is moved toward the other shuttle-box, and means operating to eject the filling carrier on the return movement of the shuttle when the fill ing carrier remains improperly positioned.

5. In a loom, the combination of a lay, a shuttle-box at the end of the lay, a deflector extending over the top of the shuttlebox, said deflector having a contacting surface inclined downwardly in a direction toward the center of the lay to contact with the end of a filling carrier improperly positioned in the shuttle.
